Sleep and treatment response in depression: new findings using power spectral analysis.

This study examined quantitative measures of sleep electroencephalogram (EEG) and phasic rapid eye movements (REM) as correlates of remission and recovery in depressed patients. To address correlates of remission, pre-treatment EEG sleep studies were examined in 130 women outpatients with major depressive disorder treated with interpersonal psychotherapy (IPT). To address correlates of recovery, baseline and post-treatment EEG sleep studies were examined in 23 women who recovered with IPT alone and 23 women who recovered with IPT+fluoxetine. Outcomes included EEG power spectra during non-rapid eye movement (NREM) sleep and REM sleep and quantitative REMs. IPT non-remitters had increased phasic REM compared with remitters, but no significant differences in EEG power spectra. IPT+fluoxetine recoverers, but not IPT recoverers, showed increases in phasic REM and REM percentage from baseline to recovery. In NREM sleep, the IPT+fluoxetine group showed a decrease in alpha power from baseline to recovery, while the IPT group showed a slight increase. The number of REMs was a more robust correlate of remission and recovery than modeled quantitative EEG spectra during NREM or REM sleep. Quantitative REMs may provide a more direct measure of brainstem function and dysfunction during REM sleep than quantitative sleep EEG measures.

Initial recovery patterns may predict which maintenance therapies for depression will keep older adults well.

BACKGROUND: Although active maintenance treatments appear superior to placebo in preventing depression recurrence in older adults, few data are available to guide maintenance modality selection to maximize the probability of continued wellness for a given patient. Patients' temporal patterns of acute treatment response may predict who requires which maintenance therapy to remain well. METHODS: Depression levels were observed over 16 weeks of combined nortriptyline (NT) and interpersonal psychotherapy (IPT) in 140 persons aged >or=60 years with recurrent major depression. Subjects were empirically classified into four groups: rapid, sustained responders; delayed, sustained responders; mixed responders without sustained improvement; prolonged nonresponders. Groups were compared on subsequent recovery rates and on time to depression recurrence after randomization to 3 years of combined maintenance therapy (monthly IPT with NT), monotherapy (either IPT or NT alone), or medication clinic with placebo. Pretreatment psychosocial and clinical variables were controlled. RESULTS: Initial response profile predicted ultimate recovery rates, as well as who remained well, given the maintenance treatment received. Rapid initial responders showed lower recurrence risk with either combined or monotherapy, relative to placebo. Specific types of monotherapy appeared equally effective in rapid responders. In initially mixed responders, only combined therapy was superior to placebo. It was marginally superior to monotherapy. For delayed responders, combined therapy was superior to placebo; monotherapy did not differ from the other maintenance conditions. Prolonged nonresponders did not benefit from maintenance treatment. LIMITATIONS: Subjects had only recurrent, unipolar depression. Initial response profile groups were established empirically and require replication. Sample sizes in initial response profile by maintenance treatment cells were small. CONCLUSION: The ability to match patients to maintenance treatments more likely to prevent recurrence may be enhanced by considering the temporal profile of initial response to acute treatment.

Truth-telling versus hope: a dilemma in practice.

This paper presents a brief outline of the attributes and therapeutic nature of hope in the context of truth-telling. It is suggested that, in some circumstances, withholding the truth to protect hope can be considered a morally acceptable option when truth-telling has the potential to destroy hope's therapeutic effects. A clinical vignette that highlights how the practitioner can be confronted with a clash of principles is presented. The possible consequences of both truth-telling and the withholding of truth are discussed and the moral positions of the health-care professionals involved are examined. This article is intended to provide a framework for discussion/group work, particularly at undergraduate level.

Weight change in older depressed patients during acute pharmacotherapy with paroxetine and nortriptyline: a double-blind randomized trial.

The authors examined weight change in 32 elderly patients treated for 12 weeks with either nortriptyline or paroxetine during acute-phase pharmacotherapy. Random assignment to treatment and double-blind assessment of weight change were performed, including ascertainment of premorbid (i.e., pre-depression) weight. Pretreatment severity of depression was correlated with weight loss during the depressive episode and depression-related weight loss, in turn, correlated with weight regained during antidepressant treatment. There was no differential weight change associated with nortriptyline vs. paroxetine. Rather, subjects in both groups approximated their premorbid weights by 12 weeks of acute-phase pharmacotherapy with either agent. However, additional investigation of weight change during continuation and maintenance pharmacotherapy is necessary and would be clinically useful for the long-term management of elderly patients with depression.

Aetiology of nasopharyngeal glioma.

A case of nasopharyngeal glioma is presented in which the postnatal scans clearly show intracranial communication, whilst subsequent scans and surgical exploration could not demonstrate this finding. This case seems to confirm that the aetiology of these lesions is due to an encephalocele that subsequently loses its connection with the brain.

Emergency care in Namibia.

Namibia is a sparsely populated nation in southwest Africa. A state-run health service provides care to most of the population. The geography and population distribution dictate the delivery systems for prehospital and emergency care. A state-run ambulance service provides basic patient transportation to the state-run hospitals. There is no 911 system. Two private aeromedical companies in Namibia provide the full range of ground and aeromedical treatment, diver rescue, and helicopter and fixed-wing transport services. The scope of care includes cricothyrotomies, chest tubes, and rapid-sequence intubation. Equipment is modern and virtually identical to what is used in the United States. There are no emergency physicians in Namibia. General medical officers are the backbone of the state-run health service. General medical officers assigned to cover the ED are called casualty officers. No specialized training beyond internship is required, and assignments to casualty are viewed as temporary until better positions become available. Only the largest state hospital in the capital has a dedicated, 24-hour emergency staff. The private prehospital care/transport systems are well organized and sophisticated. Formal efforts should be undertaken to develop ties with our colleagues in Namibia. Potential areas for collaboration include injury surveillance and prevention, field trauma resuscitation, and prehospital care.

Which elderly patients with remitted depression remain well with continued interpersonal psychotherapy after discontinuation of antidepressant medication?

OBJECTIVE: This study was conducted to identify which elderly patients with remitted recurrent major depression remain well with maintenance interpersonal psychotherapy after discontinuation of active antidepressant medication (nortriptyline). METHOD: The authors examined outcomes of maintenance therapy over 1 year for 47 elderly patients who were randomly assigned to monthly maintenance interpersonal psychotherapy with placebo (N = 19) or to placebo and a supportive medication clinic without interpersonal psychotherapy (N = 28). A Kaplan-Meier survival analysis was performed on the basis of treatment assignment and subjective sleep quality assessed by the Pittsburgh Sleep Quality Index, on which good subjective sleep quality is indicated by a score of 5 or lower. RESULTS: Nine (90%) of 10 patients reporting good subjective sleep quality (by 1 month into continuation treatment) remained well for at least 1 year when treated with monthly maintenance interpersonal psychotherapy, versus five (31%) of 16 patients with good sleep quality assigned to a medication clinic, three (33%) of nine patients with impaired sleep quality treated with maintenance interpersonal psychotherapy, and two (17%) of 12 patients with impaired sleep quality assigned to a medication clinic. CONCLUSIONS: Recovery of good subjective sleep quality by early continuation treatment is useful in identifying which remitted elderly depressed patients will remain well with monthly maintenance interpersonal psychotherapy, following discontinuation of antidepressant medication, and which patients may be more vulnerable to recurrence of major depressive episodes in the absence of antidepressant medication.

High relapse rate after discontinuation of adjunctive medication for elderly patients with recurrent major depression.

OBJECTIVE: The authors documented outcomes of elderly depressed patients requiring adjunctive medication during acute-phase pharmacotherapy because of slow or partial response to nortriptyline. Twenty-eight patients (17.7%) received inpatient care at some point during acute-phase treatment. METHOD: Rates of response, relapse, and sustained remission were examined in 158 elderly patients with recurrent major depression, grouped by whether they received brief treatment with adjunctive medication (lithium, perphenazine, or paroxetine) (N = 39) or did not (N = 119). RESULTS: The group receiving adjunctive medication had a lower rate of response to acute therapy (64.1% versus 83.2%), a higher relapse rate during continuation therapy (52.0% versus 6.1%), and a lower rate of sustained remission (recovery) (48.7% versus 76.5%) than did the group without augmentation. CONCLUSIONS: Elderly depressed patients requiring augmented pharmacotherapy to achieve remission may need continuation of adjunctive medication to remain well and to avoid early relapse. Alternatively, factors that lead to augmentation in the first place (e.g., heightened anxiety) may also increase the risk of relapse.
